China's Tianwan 7 connected to the grid - World Nuclear News

Tianwan 7, a 1.117 GW pressurised water reactor in China's Jiangsu province, has been connected to the grid. It is part of China's rapid nuclear build program, which now operates 24 reactors and has more under construction.

Where this fits

China is deploying firm, low-emission nuclear power as industrial policy while Australia maintains a legal ban on nuclear generation. Tianwan 7 represents the kind of energy-dense, long-lived asset that anchors a reliable grid and requires minimal material throughput per unit of capacity. It demonstrates that nuclear construction timelines and costs are achievable in a jurisdiction with policy certainty. Australia's renewable transition, by contrast, relies on weather-dependent generation that demands substantial firming capacity, transmission overbuild, and battery storage, all with supply chains owned or controlled by China and dependent on its coal-powered manufacturing base.

What it means

Australia is outsourcing both its power generation technology and its grid stability to a strategic rival. China builds firm power at home while exporting the variable-output, supply-chain-dependent assets that force Australian grids toward dependence on gas and battery storage. The ban on nuclear generation is not a climate policy; it is a policy that locks Australia into costlier whole-system solutions, slower decarbonisation, and deeper supply-chain exposure to Beijing. Each new Chinese reactor underscores what Australia is choosing not to build.
